Car crash test analyses the performance of a car structure deforming during the collision, shock absorbed by the material and crashworthiness of the vehicle. In this study, a simulated car crash test is performed on the Toyota Yaris car FE model for determining the effect of the material AA6082-T6 on the crashworthiness of the vehicle. The Cowper–Symonds material model is used which is very efficient in taking into account the coupled effects of strain, strain rate on the flow stress behaviour of the material. The tensile testing of AA6082-T6 material was done on Universal Testing Machine under varying strain rates of 0.0001/s, 0.001/s, 0.01/s and 0.1/s. Simulated car crash tests are widely performed for determining the degree of safety provided to the occupants of the car. In this study, all the standards set by NCAP had been used for a full-frontal crash test. The FE analysis of the car CAD model was done using LS-DYNA software and the energy absorption of the material, crash pulse of the vehicle and the velocity of the driver seat are observed and compared. The weight of the vehicle has been reduced by 1.3% and the crashworthiness of the vehicle has also been improved.
